Other objects, advantages, and meritorious The air which enters the burner is taken from features of my invention will more fully appear within the oven as shown more particularly in from the following description, appended claims, Figs. 4, 5 and 6. The air intake into the oven is and accompanying drawings, wherein: hereinafter described but it will be noted that the Figure 1 is a perspective of a cabinet embodyoven wall is provided with air exhaust openings 45 ing my invention, 22 as shown in Figs. 3, 5 and 6. Air flows through Fig. 2 is a horizontal sectional view through these openings 22 through the oven wall and is the cabinet looking down on the top of the oven, directed by a by-pass or jacket element 24 into Fig. 3 is an end View of the oven, the openings 20 that lead into the burners. This Fig. 4 is a plan view of the oven partly broken construction is shown more particularly in Figs. 5 away, 4 and 5. In this way it will be seen that the Fig. 5 is a sectional view taken on line 5-5 air pressure within the burner is maintained subof Fig. 4, stantially at the same point as the air pressure Fig. 6 is a sectional View taken on line 6-5 outside the burner upon the jets. 5, of Fig. 5, and It was found that where the burner was fed 5 with air from Without the oven that the closing of the oven doors frequently blew out the gas at the jets. With the type of construction here shown the closing of the oven door raises the pressure within the burner in the same manner as it does at the jets outside of the burner and the blowing out of gas does not result.

The oven is provided with an air intake through a conduit 26 which leads from the shelf l2 that extends upwardly from the partition into the bottom of the oven as particularly shown in Fig. 5. This conduit is also shown in Figs. 1 and 7. The oven is provided with an inner bottom wall 28 spaced above the outer bottom wall of the oven and provided with perforations 30. These perforations extend along the margin of the bottom wall on all sides. On the front adjacent the oven door they open directly into the interior of the oven compartment but along the back and the ends of the oven they open into a jacketed wall portion as shown particularly in Fig. 5. Each side wall of the oven is provided with an inner side wall member 32 spaced inwardly from the outer wall of the oven. The space between the inner wall and the outer wall member is normally filled with insulation 34 as shown in Figs. 4, 5, and 6. This insulation, however, does not extend entirely to the bottom wall member 28 as shown in Fig. 5. The inner wall members 32 are provided with perforations 36 adjacent the floor. The air which enters through the openings 30 into the space between the inner and outer side wall members escapes through the inner wall apertures 36 into the interior of the oven. This air after it has passed over the gas burner and the several shelves 38, which may be provided within the oven in number and form as desired, escapes through the ceiling 453 of the oven through apertures 42. This ceiling 40 is an inner ceiling spaced below the top of the oven and it will be noted that the insulation 34 extends along the top of the oven but is held up above the ceiling 4D to provide an air passageway thereunderneath. This ceiling 40 and the inner side walls of the oven may be provided with flanges or webs adapted to space these wall elements from the outer wall elements to provide air passageways or to provide insulation spaces as shown.

The oven is provided with a flue 44 which conducts the hot air from the space above the ceiling 40 into the top of the cabinet. The hot gases from the oven as well as from the grate within the cabinet below the oven escape through the top of the cabinet through the cabinet flue 45. This cabinet flue has a diameter preferably substantially twice that of the oven flue. The oven flue terminates within the cabinet spaced below the cabinet flue. The upper end of the cabinet is open around the oven to permit the escape of gas around the side wall of the oven from the gas range below the oven through the cabinet flue.

It will be noted that the back wall of the oven and the end wall adjacent the end of the cabinet are spaced from the side walls of the cabinet as shown particularly in Figs. 2, 4 and 5 so as to provide an air passageway 46 between the oven wall and the cabinet wall for the passage of air from the gas grate below the oven upwardly into the upper portion of the cabinet for escape through the cabinet flue. The front and end wall of the oven are provided with a depending skirt 5!] adapted to direct the gas toward the cabinet wall for escape upwardly thereabove.

In the operation of the structure some of the air which enters through louvres l6 or otherwise into the lower portion of the cabinet below the partition 10 passes upwardly over the gas grate H and through the upper compartment around the oven and particularly between the side wall of the cabinet and oven through passageway 46 to escape through the cabinet flue. A certain portion of this air which enters the lower portion of the cabinet is collected and taken by the conduit 26 into the bottom of the oven to flow into the interior of the oven through the floor and through the side walls adjacent to the floor and passes upwardly through the oven to escape through the ceiling apertures 42 and through the oven flue 44 into the upper end of the cabinet. This air which flows through conduit 26 into the oven is fresh air from below the partition It) and unmixed with products of combustion from gas grate ll. As described, a certain portion of the air is led from the interior of the oven through the apertures 22 in the end wall thereof and directed by the by-pass member 24 to enter with the gas into the end of the burner 15.. Burning gas escapes from the gas jets H. The gas escapes from the oven as hereinabove described.
